Abstract

Results of research of anticorrosion Plasma Electrolytic Oxidation (PEO) coatings for marine equipment are presented. The influence of PEO layers and surface conditions on the intensity of corrosion processes using electrochemical impedance spectroscopy, differential thermal analysis and thermal gravimetric analysis was established. PEO-coatings on low carbon steel, aluminum, titanium and magnesium alloys have been investigated. Anticorrosion properties of such layers are also improved in comparison with the untreated samples. The values of polarization resistance and impedance modulus are more than five times higher and corrosion current is six times lower than for the bare metal.
